This volume of Facture, a biennial journal that presents the latest conservation research on works of art at the National Gallery of Art, Washington, focuses exclusively on conservation treatment, technical art history, and scientific research related to masterpieces by the beloved French artist Edgar Degas (1834–1917).  The National Gallery’s extraordinary collection of sculptures, paintings, and works on paper by Degas, including an incomparable group of his wax sculptures—among them his iconic Little Dancer Aged Fourteen—allows the institution to contribute significantly to understanding the artist’s methods and intentions. This volume features discussions of the notion of “finish” in Degas’s paintings, the complex makeup of his wax sculptures, the casting of posthumous bronzes, his innovative use of multiple layers of pastel and fixative in a late work on paper, and even a sonnet that Degas wrote to his “little dancer.” Distributed for the National Gallery of Art, Washington
